1. Laser Interlock Mechanism
• Loading s
w
itch
(
S101 on the LOAB Assy
)
is used for interlock
mechanism of the laser.
When this s
w
itch turned O
N
in SW2
(
CLOS
E)
side
(
OP
EN
signal is
0
V
and CLOS
E
signal is 3.5
V)
, a laser becomes the status
w
hich can
completely
oscillation.
Furthermore, the laser completely oscillates in the disc judgment and
disc
playback.
When player is po
w
er O
N
state and laser diode is not completely
oscillating, 780nm laser diode is al
w
ays oscillating by half po
w
er.
• Laser diode is driving
w
ith
Q
307
(
650nm L
D)
and
Q
308
(
780nm L
D)
on
the
DVD
M Assy.
Therefore,
w
hen short-circuit bet
w
een the emitter and collector of these
transistors or the base voltage is supplied for transistors turn on, the
laser
oscillates.
(
failure mode
)
• In the test mode
∗
, there is the mode that the laser oscillates except
for the disc judgment and playback. L
D
O
N
mode in the test mode
oscillates
w
ith the laser forcibly.
The interlock mechanism mentioned above becomes invalid in this
mode.
2. When the cover is open, close vie
w
ing through the objective lens

ill cause exposure to the laser beam.
